Description

Technical Field

[0001] This utility model relates to a battery box structure and belongs to the field of battery box technology. Background Technology

[0002] A battery enclosure is a shell structure made of engineering materials or metal-like materials to house battery cells. When installed on a vehicle to provide power, it is often necessary to make holes in the battery enclosure and use wires or cables to lead out the current from the battery inside the enclosure to ensure normal power supply.

[0003] However, when the battery box is used in a vehicle environment, it will be subjected to significant and continuous vibration when the vehicle is in motion. This can cause the wires to rub against the walls of the openings, resulting in damage to the surface of the wires and causing short circuits or leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a battery box structure that utilizes protective components to achieve double isolation protection for wires, preventing short circuits or leakage; furthermore, the protective components are firmly connected and fixed to the box body, making them less likely to fall off in a vibrating environment.

[0005] This utility model is achieved through the following technical solution.

[0006] A battery box structure includes a box body with a through hole allowing wires to pass through. The through hole has a protective component made of insulating material for isolating the wires from the box body. The protective component includes a first protective member inside the box body and a second protective member outside the box body. The first and second protective members each have a first and a second axially oriented protective channel. The first protective member is at least partially embedded in the through hole for circumferential positioning. The first protective member is detachably sleeved on the second protective member to allow communication between the first and second protective channels, and a first limiting member formed on the first protective member abuts against the inner wall of the box body, and a second limiting member formed on the second protective member abuts against the outer wall of the box body.

[0007] As a further improvement of this utility model, the first protective component and the second protective component are threadedly connected, the first protective component is provided with an internal thread, and the second protective component is provided with an external thread that mates with the internal thread.

[0008] As a further improvement of this utility model, the outer peripheral surface of the second limiting member is formed with an operating part suitable for controlling the rotation of the second limiting member along the axis.

[0009] As a further improvement of this utility model, the outer peripheral surface of the second limiting member is formed into a regular hexagonal structure.

[0010] As a further improvement of this utility model, when the second limiting member abuts against the outer wall of the box, the end of the second protective member near the box is located inside the first protective member.

[0011] As a further improvement of this utility model, a plurality of positioning surfaces are formed on the outer surface of the first protective component. The plurality of positioning surfaces constitute a positioning structure that cooperates with the hole wall of the through hole, so that the first protective component cannot rotate circumferentially relative to the box body.

[0012] As a further improvement of this utility model, the second limiting member is formed on the end of the second protective component away from the housing.

[0013] As a further improvement of this utility model, the first limiting member is formed at the end of the first protective member away from the second protective member.

[0014] As a further improvement of this utility model, the first protective component and the first limiting component are integrally formed; the second protective component and the second limiting component are integrally formed.

[0015] The beneficial effects of this utility model are:

[0016] 1. The first protective component and the second protective component are fitted together to form double insulation protection for the wires passing through the through hole, effectively isolating the wires from the enclosure and preventing short circuits or leakage.

[0017] 2. The first protective component is embedded in the through hole to achieve circumferential positioning of the first protective component, preventing the first protective component from rotating or shifting, and facilitating the installation of the first protective component; in addition, the first limiting member abuts against the inner wall of the box and the second limiting member abuts against the outer wall to fix the protective component, which enhances the structure's vibration resistance and is suitable for frequent vibration scenarios of vehicle battery boxes.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0025] This embodiment provides a battery box structure suitable for vehicle environments, see reference. Figures 1-4 The device includes a housing 1, the interior of which has a space for holding batteries. The housing 1 has a through hole 11 that allows wires m to pass through. The through hole 11 has a protective component made of insulating material to isolate the wires m from the housing 1. The protective component includes a first protective component 21 located inside the housing 1 and a second protective component 22 located outside the housing 1. The first protective component 21 and the second protective component 22 have a first protective channel 21a and a second protective channel 22a respectively opened along the axial direction. The first protective component 21 can be at least partially embedded in the through hole 11 to achieve circumferential positioning. The first protective component 21 is detachably sleeved on the outside of the second protective component 22 so that the first protective channel 21a and the second protective channel 22a are connected, and a first limiting member 23 formed on the first protective component 21 abuts against the inner wall 12 of the housing 1, and a second limiting member 24 formed on the second protective component 22 abuts against the outer wall 13 of the housing 1.

[0026] The first protective component 21 and the second protective component 22 are sleeved together to form double insulation protection for the wire m passing through the through hole 11, effectively isolating the wire m from the box 1 and preventing short circuits or leakage.

[0027] The first protective component 21 is embedded in the through hole 11 to achieve circumferential positioning of the first protective component 21, preventing the first protective component 21 from rotating or shifting, and facilitating the installation of the first protective component 21; in addition, the first limiting member 23 abuts against the inner wall 12 of the box body 1 and the second limiting member 24 abuts against the outer wall 13 of the box body 1 to achieve the fixation of the protective component, which enhances the structure's vibration resistance and is suitable for frequent vibration scenarios of vehicle battery boxes.

[0028] In addition, the first protective component 21 and the second protective component 22 are detachably connected, which facilitates later maintenance and replacement.

[0029] In this embodiment, the first protective component 21 and the second protective component 22 can be threaded together. Specifically, the inner wall 12 of the first protective component 21 is provided with an internal thread 21b, and the outer wall 13 of the second protective component 22 is provided with an external thread 22b that mates with the internal thread 21b of the first protective component 21. The first protective component 21 and the second protective component 22 can be detachably connected by rotating the second protective component 22, and the structure has high strength after the connection. In addition, since the first protective component 21 is positioned on the housing 1, the first protective component 21 will not be rotated when the second protective component 22 is rotated, eliminating the need for additional fixing of the first protective component 21 and simplifying the installation of the protective components.

[0030] Furthermore, when rotating the second protective component 22, in order to ensure that the second limiting member 24 fits tightly against the outer wall 13 of the housing 1, a tool is generally used to rotate the second limiting member 24. This tool can be a wrench or pliers. Therefore, an operating part suitable for controlling the rotation of the axis of the second limiting member 24 can be formed on its outer peripheral surface. The tool can directly contact the outer peripheral surface of the second limiting member 24 to clamp the second protective component 22. The outer peripheral surface of the second limiting member 24 can have a regular hexagonal structure to facilitate tool control. It should be noted that the second limiting member 24 should have a certain thickness along the axial direction to ensure sufficient contact between the tool and the outer peripheral surface of the second protective component.

[0031] In other embodiments, the first protective component 21 and the second protective component 22 may be fitted with a slot and a tooth or with an interference fit, so that the second protective component 22 can extend into the first protective component 21 and achieve a detachable connection between the two, while the protective component can be fixed to the housing 1.

[0032] In this embodiment, when the second limiting member 24 abuts against the outer wall 13 of the housing 1, the end of the second protective member 22 near the housing 1 is located inside the first protective member 21, which can prevent the second protective member 22 from protruding outside the first protective member 21, thereby reducing the installation space.

[0033] In this embodiment, the first limiting member 23 is formed at the end of the first protective member 21 away from the second protective member 22. Therefore, when the first limiting member 23 abuts against the inner wall 12 of the housing 1, the occupancy of the first protective member 21 on the internal space of the housing 1 is reduced. Furthermore, the second limiting member 24 is formed on the end of the second protective member 22 away from the housing 1, which can reduce the occupancy of the second protective member 22 on the external space of the housing 1.

[0034] In this embodiment, the outer surface of the first protective component 21 has a plurality of positioning surfaces 25. The plurality of positioning surfaces 25 constitute a positioning structure that cooperates with the hole wall of the through hole 11, so that the first protective component 21 cannot rotate circumferentially, thereby achieving axial positioning of the first protective component 21. The plurality of positioning surfaces 25 here constitute a regular quadrilateral or regular hexagonal structure, which can restrict the first protective component 21 from rotating relative to the housing 1.

[0035] In this embodiment, the first protective component 21 and the first limiting component 23 are integrally formed, and the second protective component 22 and the second limiting component 24 are integrally formed. Both can be injection molded from insulating plastic (such as PET or PVC) to ensure electrical isolation between the wire m and the housing 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
