Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a battery reinforcement box structure for electric vehicles. Background Technology

[0002] The battery box of an electric vehicle is a device used to load and protect the battery. It is usually located at the bottom of the vehicle or under the foot pedal. The main function of the battery box is to fix the battery and prevent it from being damaged by vibration and collision during driving, while ensuring the safe use of the battery.

[0003] The risk of battery damage under extreme conditions such as collisions and compression can threaten the safety of drivers and passengers. Batteries need to be used in a good environment. Batteries may be damaged due to vibration, temperature differences, etc., so we have improved the above-mentioned existing technologies based on actual usage. Utility Model Content

[0033] Please see Figure 1-4 This utility model provides a technical solution: an electric vehicle battery reinforcement box structure, including a reinforcement box 1, a battery box 2, a restraint component 3, a fixing ear 4, and a concave groove 8;

[0034] The reinforcing box 1 is a square box structure with an opening at the top. The top of the reinforcing box 1 is connected to a reinforcing structure 6, which is arranged around the top of the reinforcing box 1 to improve its functionality. The inner walls of the reinforcing box 1 are connected to reinforcing plates 101 on both the front and back sides. The bottom of the reinforcing box 1 has mounting holes 103 at the four corners to fix the reinforcing box 1 to the electric vehicle, which makes the whole device very stable. The bottom of the reinforcing box 1 is provided with a support plate 104.

[0035] Battery box 2 is placed inside the cavity of reinforcing box 1. Rubber plates are inserted vertically at the four corners of reinforcing box 1 to stabilize the battery box 2. Battery box 2 is also equipped with a battery cover plate 21 on top.

[0036] The restraint assembly 3 consists of two identical structures, and the two restraint assemblies 3 are installed on the top of the reinforcement box 1. The bottom of the restraint assembly 3 is attached to the top of the battery cover 21 to fix the battery box 2 and prevent it from being bumped on bumpy roads, so that it can be stored more stably in the reinforcement box 1.

[0037] The fixing ears 4 are two sets of identical structures, and the two sets of fixing ears 4 are symmetrically installed on the outer walls of the left and right sides of the reinforcing box 1. The fixing ears 4 are provided with fixing ear holes 5. The entire device can be fixed to the electric vehicle together with the mounting holes 103 through the fixing ear holes 5.

[0038] The concave groove 8 consists of four identical structures, and the four concave grooves 8 are symmetrically arranged on the front and rear reinforcing structures 6. Each concave groove 8 has a limit block 9 connected to its inner cavity.

[0039] It should be noted that the reinforcing box 1 is installed on the electric vehicle through the mounting hole 103 and the fixing ear hole 5. After the battery box 2 is installed, it is fixed and limited by two sets of restraint components 3 to ensure its stability. The setting of the reinforcing structure 6 ensures that the opening of the reinforcing box 1 will not change due to the thermal expansion and contraction of plastic, and the battery box 2 can be easily stored in the reinforcing box 1.

[0040] Preferably, the reinforcing structure 6 is a frame structure, integrally formed with the top of the reinforcing box 1. A wire harness loop 102 is provided on the front reinforcing structure 6 to facilitate the power cord 23 to pass through and provide power to the electric vehicle. An installation socket 7 is connected to the top of the left reinforcing structure 6, which can be used to install the electric vehicle's fuse or controller (existing structure, not shown in the figure).

[0041] Preferably, rubber strips 105 are evenly arranged on the support plate 104. When the battery box 2 is placed into the reinforcing box 1, the rubber strips 105 increase the bottom friction of the battery box 2, providing it with stability. At the same time, because the spaced rubber strips 105 form gaps with the bottom of the battery box 2, they also play a certain role in heat dissipation.

[0042] Preferably, the top of the battery box 2 is provided with two sets of terminals 22, and power cords 23 are connected to the terminals 22. The structure and principle of the battery box 2 are existing technologies and will not be described in detail.

[0043] Preferably, the restraint assembly 3 includes a restraint plate 31. Two sets of identical connecting ears 32 are connected to the bottom front end of the restraint plate 31, and the connecting ears 32 are provided with shaft holes 33. Bolts are connected to the limiting blocks 9 in the inner cavities of the two sets of concave grooves 8 on the front side, and the bolts pass through the limiting blocks 9 and are installed in the shaft holes 33. The connection of the bolts facilitates the installation of the connecting ears 32 and the limiting blocks 9 on the front side. At the same time, the restraint plate 31 can be opened and closed through the connecting ears 32, which facilitates the removal and placement of the battery box 2.

[0044] Preferably, a buckle 34 is connected to the bottom rear side of the binding plate 31, and a buckle groove matching the buckle 34 is connected to the limiting block 9 in the inner cavity of the two sets of concave grooves 8 on the rear side. The buckle 34 and the buckle are existing technologies. Through their cooperation, the binding plate 31 can be used to bind and install the battery box 2. A rubber plate 35 is connected to the bottom of the binding plate 31. Ventilation holes are evenly opened on the rubber plate 35, and the bottom of the rubber plate 35 is in contact with the top of the battery cover 21. The rubber plate 35 with ventilation holes is pressed tightly against the surface of the battery cover 21 to protect the battery cover 21 from being damaged by too much pressure.

[0045] It should be noted that the electrical component of this utility model is used to organize the wire harness during operation, and will not cause the wire harness to become tangled.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
