Technical Field

[0001] This utility model relates to a battery box, and more particularly to a top cover of a battery box and the battery box itself. Background Technology

[0002] The battery box in a car is a device used to protect the battery, and the layout of battery boxes varies from car manufacturer to car manufacturer. Multiple battery packs are arranged inside the battery box, and the battery packs are connected by copper busbars. Due to advancements in battery technology, there are now various data acquisition lines inside the battery box. All lines are output through the side panel or end cover of the battery box. For example, the battery box cover, battery box, and battery disclosed in CN219801225U, although not explicitly stating the line entry points, allows those skilled in the art to clearly deduce the corresponding design scheme from the accompanying drawings. This design involves two line entry points, and the lines must converge after extending out of the battery box, resulting in a complex wiring configuration. Furthermore, this type of battery box has poor heat dissipation and low structural strength. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a top cover for a battery box.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0005] A battery box cover includes a cover body covering the battery box body, an inner cavity for mounting, a groove for the outer side of one end of the cover body, a window communicating with the mounting cavity on the side wall of the groove, a notch on the side wall of the cover body communicating with the groove, a pressure block for pressing the circuit installed at the notch, and a claw on the side wall of the notch, the pressure block engaging with the claw.

[0006] Preferably, the cover body has an inwardly protruding positioning post integrally formed, the positioning post being a centrally shaped tube, and the through hole on the positioning post communicating with the groove.

[0007] Preferably, a portion of the through-hole is formed on the sidewall of the groove, while another portion of the through-hole is located at the bottom of the groove.

[0008] Preferably, one side wall of the cover is provided with at least two latches, and the other end of the cover is provided with studs for connection with fasteners.

[0009] Preferably, the upper surface of the cover is wavy.

[0010] Preferably, the end face of the cover is provided with a number of first heat dissipation holes, all of which are arranged in a rectangular array. The bottom of the groove is provided with a number of second heat dissipation holes, all of which are arranged in a rectangular array. Both the first and second heat dissipation holes are connected to the mounting cavity.

[0011] Preferably, the upper surface of the cover is provided with upwardly protruding reinforcing ribs, and there are multiple reinforcing ribs, all of which are located in the middle of the cover and arranged on the same straight line.

[0012] Preferably, a number of positioning protrusions are provided on the side wall of the cover.

[0013] Preferably, the cover has positioning grooves that extend through its upper and lower ends on multiple side walls.

[0014] A battery box includes a box body and a top cover of the battery box, the top cover being closed onto the box body.

[0015] This utility model, by adopting the above technical solution, has significant technical effects:

[0016] The battery box cover has a dedicated wiring channel. After the wiring extends through the window, it is further integrated by a clamping block, so that the wiring extending out of the cover is neat and not messy.

[0017] The top cover is also equipped with hollow positioning posts. These posts are not only used to position the top cover on the battery box, but also allow some special lines to extend from the hollow channels of the positioning posts, resulting in a reasonable wiring layout.

[0018] The top cover has multiple reinforcing ribs, resulting in high strength.

[0019] The top cover has ventilation holes, which improves the heat dissipation of the battery box. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail with reference to the embodiments.

[0026] Example 1

[0027] A battery box cover includes a cover body 1 covering the battery box body. The cover body 1 has an inner mounting cavity 11, and a downwardly recessed groove 12 on the outer side of one end of the cover body 1. The groove 12 is a stepped groove, and the side of the groove 12 near the cover body 1 has no sidewall. The sidewall of the groove 12 has a window 13 communicating with the mounting cavity 11. The window 13 is a square through hole. The sidewall of the cover body 1 has a notch 14 communicating with the groove 12. A clamping block for pressing the wires is installed at the notch 14, and a claw 15 is provided on the sidewall of the notch 14. The clamping block and the claw 15 are engaged. The wires extend from the window 13 and enter the groove 12, then extend from the notch 14. All the wires are limited by the clamping block at the notch 14, thus ensuring a clear and uncluttered wire layout.

[0028] The cover 1 has an integrally formed inwardly protruding positioning post 16, which is a centrally located tube. The through hole 161 on the positioning post 16 communicates with the groove 12. The positioning post 16 is not only used for positioning and installation with the battery box, but some wires inside the battery box can also extend into the groove 12 through the channel of the positioning post 16.

[0029] A portion of the through hole 161 is formed on the side wall of the groove 12, while another portion of the through hole 161 is located at the bottom of the groove 12. The wires extending from the through hole 161 of the positioning post 16 can quickly enter the groove 12 without the need for other wire grooves.

[0030] The cover 1 has at least two latches 17 on one side wall. In this embodiment, there are two latches 17. The cover 1 is engaged with the battery box through the latches 17. The other end of the cover 1 has a stud 18 for fastening screws, thereby securing the cover 1 to the battery box. By fixing the cover 1 to the battery box through two installation methods, the cover 1 is not only easy to install, but also has high connection reliability.

[0031] The upper surface of the cover 1 is wavy, and the wavy cover 1 has high strength and is not easy to break.

[0032] The end face of the cover 1 is provided with a number of first heat dissipation holes 19, all of which are arranged in a rectangular array. The bottom of the groove 12 is provided with a number of second heat dissipation holes 20, all of which are arranged in a rectangular array. Both the first heat dissipation holes 19 and the second heat dissipation holes 20 are connected to the mounting cavity 11. The first heat dissipation holes 19 and the second heat dissipation holes 20 can quickly dissipate heat from the battery box, thus achieving rapid cooling.

[0033] The cover 1 has a number of positioning protrusions 22 on its side wall. There are three positioning protrusions 22. The cover 1 is engaged with the battery box by the positioning protrusions 22 to ensure the stability of the cover 1 during installation.

[0034] The cover 1 has positioning grooves 23 on multiple side walls that extend through its upper and lower ends. The positioning grooves 23 assist in positioning and installing the cover 1 to ensure its stability.

[0035] Example 2

[0036] Example 2 is basically the same as Example 1, except that the upper end face of the cover 1 is provided with an upwardly protruding reinforcing rib 21. There are multiple reinforcing ribs 21. In this example, there are four reinforcing ribs 21. All reinforcing ribs 21 are located in the middle of the cover 1 and are arranged on the same straight line.

[0037] Example 3

[0038] A battery box includes a box body and a top cover of the battery box in embodiment 1 or 2, the top cover being closed onto the box body.
