Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a battery mounting nut for a new energy vehicle. Background Art

[0002] New energy vehicles use unconventional automotive fuels as their power source (such as electricity, hydrogen, etc.), or use conventional automotive fuels (such as gasoline, diesel) but adopt new on-board power devices (such as hybrid systems, fuel cell systems, etc.), and combine them with advanced power control and drive technologies. The resulting vehicles have advanced technical principles, new technologies, and new structures. They mainly rely on electricity for vehicle propulsion, so batteries need to be installed on the vehicle to store and provide electrical energy.

[0003] During the installation process of new energy vehicle batteries, the cooperation between nuts and screws plays a key role and can effectively complete the fixation of the battery. Although the weight of a single nut is relatively light, if the weight of multiple sets of nuts used for battery installation is reduced, the total weight of the entire vehicle will be affected. The lighter overall weight can improve the vehicle's energy efficiency and driving efficiency, thereby potentially extending the cruising range of new energy vehicles. Therefore, considering the weight of small components such as nuts when designing and manufacturing new energy vehicles is one of the effective optimization strategies. To this end, a new energy vehicle battery installation nut is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a new energy vehicle battery mounting nut, which can solve the problem that the cooperation between nuts and screws plays a key role in the installation process of new energy vehicle batteries and can effectively complete the fixation of the battery. However, the weight of traditional nuts is relatively large. The use of these nuts and screws will cause the overall weight of the vehicle to be relatively large, which in turn can easily have an adverse effect on the vehicle's energy efficiency and endurance.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy vehicle battery mounting nut, comprising a nut body, and also comprising:

[0006] A positioning groove is provided on the outer surface of the nut body;

[0007] A thread hole is provided on the outer surface of the nut body and is located below the positioning groove;

[0008] A wrench slot is provided on the outer surface of the nut body and is located below the thread hole;

[0009] The recessed groove is opened on the outer surface of the nut body, the recessed groove is located above the wrench groove, and the recessed groove is located outside the thread hole.

[0010] Preferably, the nut body is made of stainless steel.

[0011] Preferably, the diameter of the nut body is 12.5 mm and the height is 15.6 mm.

[0012] Preferably, the positioning groove has a diameter of 5.5 mm and a depth of 2.5 mm.

[0013] Preferably, the diameter of the thread hole is 2.5 mm and the depth is 6.1 mm.

[0014] Preferably, the wrench slot is a hexagonal groove with a distance between opposite sides of 8.8 mm, a circumscribed circle diameter of 10.1 mm (based on the corner point), and a depth of 7 mm.

[0015] Preferably, the depth of the recessed groove is 5 mm, the outer edge of the recessed groove is hexagonal, the inner edge is circular, and the diameter of the circle is 5.5 mm.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This application achieves the function of reducing the weight of the nut body by setting the positioning groove, thread hole, wrench groove and innovative recessed groove. It can reduce the weight of the nut body without changing the effective depth of the wrench groove and the depth of the thread hole, ensuring that the functional role of the wrench groove and the thread hole can be fully utilized, thereby helping to reduce the overall weight of the vehicle, improve the vehicle's energy efficiency performance and driving efficiency, and provide new energy vehicles with potential advantages in extending the cruising range.
