Description

Technical Field

[0001] The utility model belongs to the field of high-temperature resistant nuts, in particular to a high-temperature resistant nut for an automobile battery pack. Background Art

[0002] With the increasing global demand for clean energy and sustainable transportation, the electric and hybrid vehicle markets are developing rapidly. One of the core components of these vehicles is the battery pack, which generates a lot of heat during operation. Excessive temperature not only affects the performance and life of the battery, but also may cause safety hazards.

[0003] Existing battery packs typically use conventional fasteners, such as nuts and bolts, to secure battery modules. However, these traditional fasteners often fail to meet requirements in high-temperature environments, and are prone to problems such as heat accumulation and nut loosening. These phenomena not only degrade battery pack performance but can also lead to safety accidents.

[0004] Therefore, in order to solve the above problems, a high temperature resistant nut for automobile battery pack is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that nuts are prone to heat accumulation and loosening in high temperature environments, a high-temperature resistant nut for an automotive battery pack is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the utility model is a high-temperature resistant nut for a car battery pack, including a nut body, a support groove is opened inside the nut body, a heat dissipation fin is arranged inside the nut body, and the support groove is also opened inside the heat dissipation fin. A convection outer ring is opened on the surface of the nut body, and the convection outer ring is opened on the side of the support groove close to the outside of the nut body. A convection inner ring is also opened on the surface of the nut body, and the convection inner ring is opened on the side of the support groove close to the inside of the nut body. The support groove and the convection outer ring are both used to expand the contact area between the nut body and the air.

[0007] Preferably, air guide grooves are provided on the upper and lower surfaces of the heat dissipating fins, and the air guide grooves are opened in a curved shape. One end of the air guide groove passes through the inner diameter side of the heat dissipating fins, and the end of the air guide groove away from the inner diameter of the heat dissipating fins passes through the outer wall of the heat dissipating fins, thereby increasing the contact area between the surface of the heat dissipating fins and the air.

[0008] Preferably, a positioning column is connected through the interior of the supporting groove, and a supporting fin is clamped on the surface of the positioning column to ensure the stability of the nut body in use.

[0009] Preferably, one end of the supporting fin away from the positioning column is sharp-edged, which reduces the shielding space outside the heat dissipation fin and provides necessary support for the heat dissipation fin.

[0010] Preferably, the length of the supporting fins does not exceed the vertical range of the surface of the nut body, and a ninety-degree angle is provided between the supporting fins, thereby ensuring air circulation between the two heat dissipation fins.

[0011] Preferably, a positioning plate is connected between the two heat dissipation fins, and a guide hole is provided on the inner side of the positioning plate close to the nut body, which enhances the stability of the nut body and improves the heat dissipation effect of the nut body.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a high-temperature resistant nut for an automobile battery pack. By arranging related structures such as a heat dissipation fin, the entire nut body can be effectively dissipated without damaging the fixing effect of the nut body itself, thereby accelerating the air circulation inside the nut body.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figures 1-4 The utility model provides a high-temperature resistant nut for an automotive battery pack, comprising a nut body 1, a support groove 2 being provided inside the nut body 1, a heat dissipation fin 5 being provided inside the nut body 1, the support groove 2 being also provided inside the heat dissipation fin 5, a convection outer ring 3 being provided on the surface of the nut body 1, the convection outer ring 3 being provided on the side of the support groove 2 close to the outside of the nut body 1, a convection inner ring 4 being provided on the surface of the nut body 1, the convection inner ring 4 being provided on the side of the support groove 2 close to the inside of the nut body 1, the support groove 2 and the convection outer ring 3 being used to expand the contact area between the nut body 1 and the air.

[0024] In this embodiment, through such a configuration, in order to improve the heat dissipation of the nut body 1 itself and to avoid thermal expansion and contraction during the installation process, thereby destroying the normal service life of the nut body 1, the heat dissipation fins 5 are opened to first expand the contact area between the side of the nut body 1 and the air. A cavity is set between the two heat dissipation fins 5, and one end of the heat dissipation fin 5 is connected to the inner wall of the nut body 1. Therefore, without destroying the use effect of the nut body 1, the surface ventilation effect of the nut body 1 can also be improved. In addition, in order to ensure the firmness of the heat dissipation fins 5 during use of the nut body 1, we set a support groove 2, and any fastener for fastening the heat dissipation fins 5 can be inserted through the inside of the support groove 2, so that the heat dissipation fins 5 can be effectively fixed, thereby ensuring the use stability of the heat dissipation fins 5 and avoiding the heat dissipation fins 5 from breaking. At the same time, the opening of the convection outer ring 3 and the convection inner ring 4 improves the surface heat dissipation effect of the nut body 1, effectively ensuring the use effect of the nut body 1.

[0025] Please refer to Figures 1-4 Air guide grooves 6 are provided on the upper and lower surfaces of the heat dissipation fins 5. The air guide grooves 6 are curved in shape. One end of the air guide grooves 6 passes through the inner diameter side of the heat dissipation fins 5, and the end of the air guide grooves 6 away from the inner diameter of the heat dissipation fins 5 passes through the outer wall of the heat dissipation fins 5.

[0026] In this embodiment, through such a setting, it can be seen that the air guide groove 6 opened on the surface of the heat dissipation fin 5 can cut the surface of the heat dissipation fin 5. It can be explained that the heat dissipation fin 5 itself has the properties of a fin, and multiple fins are arranged under the penetration and fixation of the support groove 2, so as not to damage the function of the nut body 1 itself. The existence of the air guide groove 6 can effectively expand the surface space of the heat dissipation fin 5, thereby ensuring that the air can circulate quickly inside the heat dissipation fin 5, and the air can be discharged by the air guide groove 6 when passing through the air guide groove 6. Since the air guide groove 6 itself is curved, the heat will be dissipated through the heat dissipation fin 5 while being guided by the air guide groove 6, so that the heat dissipation fin 5 can be faster.

[0027] Please refer to Figures 1-4 A positioning column 9 is connected to the inside of the support groove 2, and a supporting fin 8 is clamped on the surface of the positioning column 9. The end of the supporting fin 8 away from the positioning column 9 is sharp. The setting length of the supporting fin 8 does not exceed the vertical range of the surface of the nut body 1, and a ninety-degree angle is opened between the supporting fins 8.

[0028] In this embodiment, with such an arrangement, the positioning column 9 can effectively penetrate the interior of the support groove 2 to provide pulling support for the entire nut body 1, and the support fins 8 are clamped between the two heat dissipation fins 5. Through such an arrangement, it can be seen that the support fins 8 not only support the heat dissipation fins 5, but also ensure the strength of the heat dissipation fins 5 and can also divide the internal circulation space of the heat dissipation fins 5, ensuring that the air interaction inside and outside the nut body 1 is stronger, while improving the overall heat dissipation effect of the nut body 1.

[0029] Please refer to Figures 1-4 A positioning plate 11 is connected between the two heat dissipation fins 5 , and a guide hole 10 is opened on the inner side of the positioning plate 11 close to the nut body 1 .

[0030] In this embodiment, through such an arrangement, the nut body 1 can be formed by connecting multiple groups of heat dissipation fins 5 and positioning plates 11. The arrangement of the positioning plates 11 ensures the necessary installation effect of the nut body 1, and the opening of the guide holes 10 ensures that when the nut body 1 and the bolt are connected, the connection can still discharge airflow, thereby effectively ensuring the use effect of the device.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
