Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive batteries, specifically a battery structure with good heat dissipation. Background Technology
[0002] New energy vehicle batteries generally include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, and lead-acid batteries. Lead-acid batteries are widely used in electric vehicles due to their high reliability and low cost. Nickel-metal hydride batteries are alkaline batteries, known for their long lifespan and lack of memory effect. Lithium-ion batteries are new high-voltage, high-energy-density rechargeable batteries, offering advantages such as light weight, large energy storage capacity, and zero pollution, making them environmentally friendly. When installing new energy vehicle batteries, a support structure is needed to support and secure them to prevent movement and to protect them from debris that could affect their normal operation.
[0003] The existing technology has the following problems:
[0004] Existing battery structures have poor heat dissipation. Under normal circumstances, new energy batteries can be fixed in a box inside a car and then vents can be made in the side wall of the box to dissipate the heat generated by the new energy batteries when they are working. However, simply making vents cannot meet the heat dissipation requirements of the battery. Data shows that the capacity of lithium batteries drops significantly above 55°C and the battery life is shortened accordingly. When the ambient temperature exceeds 60°C, the battery will be at risk of overheating, burning, and exploding due to excessive temperature rise. Utility Model Content

The exhaust duct can avoid excessive friction between the blades and the battery box when the blades rotate, and can also allow the wind generated by the blades to quickly dissipate the heat generated inside the battery box due to the operation of the battery pack through the exhaust duct.
[0012] Preferably, a fixing post is fixedly connected to the bottom of the battery box, and the battery box is fixedly connected to the motor through the fixing post. The fixing post can ensure the operating stability of the motor and prevent the battery box from falling off due to vibration or other problems during the operation of the motor.
[0013] Preferably, one side of the reinforcing plate is detachably equipped with a screw, and the reinforcing plate is movably connected to the cover plate through the screw. The screw can provide stability for the reinforcement installation of the reinforcing plate and the cover plate, thereby ensuring the stability of the cover plate installation.
[0014] Preferably, the cover plate has a sliding groove on its front side, and the cover plate is movably connected to the ceramic heat-conducting plate through a slider and the sliding groove. The slider and the sliding groove allow the ceramic heat-conducting plate to be installed and removed from the cover plate by sliding, which facilitates replacement and maintenance.
[0015] (III) Beneficial Effects

[0026] A slider 8 is fixedly connected to one side of the ceramic heat-conducting plate 6, and a heat dissipation hole 10 is opened on one side of the battery box 1. A motor 12 is fixedly connected to the bottom of the battery box 1, and the output shaft of the motor 12 is fixedly connected to a rotating shaft 13 through a coupling. A blade 14 is fixedly connected to the outer wall of the rotating shaft 13, which enables the structure to facilitate heat dissipation. During the stage when the battery structure generates heat, the heat generated by the battery structure can be quickly dissipated by the combined action of exhaust and heat conduction, avoiding heat accumulation that could lead to overheating, combustion, or explosion of the battery structure. This ensures the safety of the battery structure and meets people's usage needs.
[0027] In this embodiment, there are five ceramic heat-conducting plates 6, and the five ceramic heat-conducting plates 6 are equally spaced on the top of the battery pack 2. The ceramic heat-conducting plates 6, especially the aluminum nitride ceramic substrate, have significant advantages in battery heat conduction due to their excellent thermal conductivity and insulation properties. The ceramic heat-conducting plates 6 can also be used as pads, which can effectively reduce vibration between modules and protect the battery pack 2 from impact and shock absorption. This can not only extend the battery's service life, but also improve the overall performance and safety of the electric vehicle.
[0028] Example 2
[0029] Based on Example 1, a preferred embodiment of the battery structure with good heat dissipation provided by this utility model is, for example... Figures 1 to 4 As shown: The bottom of the battery box 1 is provided with an exhaust duct, and the shape and size of the exhaust duct are matched with the shape and size of the blade 14. The exhaust duct can avoid excessive friction between the blade 14 and the battery box 1 when the blade 14 rotates, and can allow the wind generated by the blade 14 to quickly dissipate the heat generated inside the battery box 1 due to the operation of the battery pack 2 through the exhaust duct.
[0030] In this embodiment, a fixing post 11 is fixedly connected to the bottom of the battery box 1, and the battery box 1 is fixedly connected to the motor 12 through the fixing post 11. The fixing post 11 can ensure the operational stability of the motor 12 and prevent the motor 12 from falling off due to vibration or other problems during operation.
[0031] Furthermore, a screw 5 is detachably attached to one side of the reinforcing plate 4, and the reinforcing plate 4 is movably connected to the cover plate 3 via the screw 5. The screw 5 can provide stability for the reinforcing plate 4 and the cover plate 3 during installation, thereby ensuring the stability of the cover plate 3 during installation.
[0032] Furthermore, the front of the cover plate 3 is provided with a sliding groove 9, and the cover plate 3 is movably connected to the ceramic heat-conducting plate 6 through the slider 8 and the sliding groove 9. The slider 8, in conjunction with the sliding groove 9, allows the ceramic heat-conducting plate 6 to be installed and removed from the cover plate 3 by sliding, thereby facilitating replacement and maintenance.
[0033] In use, the battery pack 2 can be placed inside the battery box 1, and then the cover plate 3 can be placed on top of the battery box 1. The reinforcing plate 4 can be reinforced to the cover plate 3 using the screw 5. Then, the ceramic heat-conducting plate 6 can be slidably installed on the cover plate 3 using the slider 8 and the slide groove 9, so that the ceramic heat-conducting plate 6 is in contact with the top of the battery pack 2. When the battery pack 2 generates heat during use, the motor 12 can be turned on. The motor 12 drives the rotating shaft 13 and the blades 14 to rotate. The rotation of the blades 14 generates wind to expel the heat inside the battery box 1. At the same time, the ceramic heat-conducting plate 6 conducts heat to the top of the battery pack 2 and the heat dissipation fins 7 provide heat dissipation. The heat dissipation holes 10 provide further heat dissipation effect, thus completing the operation.
[0034] In summary, this battery structure with good heat dissipation can facilitate heat dissipation. During the phase when the battery structure generates heat, the combined effect of exhaust and heat conduction can quickly dissipate the heat generated by the battery structure, avoiding heat accumulation that could lead to overheating, combustion, or explosion. This ensures the safety of the battery structure and meets people's usage needs.
