Description

Technical Field

[0001] This utility model relates to the field of automotive battery box structure technology, specifically to a battery box wiring harness bracket mounting structure. Background Technology

[0002] As the core energy supply unit for new energy vehicles, the safety and reliability of power battery systems are receiving increasing attention. The battery housing, as the main load-bearing structure of the battery module, typically houses the battery cells and their associated electrical connection systems. In existing technologies, the bottom of the battery housing often features a crossbeam structure, dividing the interior into at least two areas: one for accommodating the battery cells, and the other for laying the wiring harness (including power lines, signal lines, etc.). This layout achieves a certain degree of physical isolation between the battery module and the wiring harness, helping to simplify the assembly process and avoid direct interference between cables and battery cells.

[0003] However, in practical applications, the above structure still has significant drawbacks. Because the connecting wires are typically simply placed within the wiring harness area without effective fixing and protection measures, during vehicle operation, especially under bumpy, vibrating, or collision conditions, the wiring harness is prone to displacement, swaying, and even frequent friction and collision with the inner wall of the battery box or the edge of the crossbeam. Over time, the insulation layer of the connecting wires may wear down, and the wire cores may become fatigued or even break, causing electrical connection failures, signal transmission interruptions, or short circuits, seriously affecting the power supply stability and safety of the battery system.

[0004] More seriously, if a vehicle experiences a sudden power outage or circuit failure due to a broken wiring harness while in motion, it may lead to loss of power or abnormal control system operation, which could then cause a traffic accident and threaten the safety of the driver and passengers. Utility Model Content

[0005] In view of this, the present invention provides a battery box wiring harness bracket mounting structure, which enables the connection wires to be installed stably and avoids wear caused by the connection wires shaking.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A battery box wiring harness bracket mounting structure includes a base plate and side beams surrounding the base plate. The base plate is also provided with a crossbeam, which divides the base plate into a battery core mounting area and a connecting wire arrangement area. The crossbeam is characterized in that: at least two hooks are riveted to the top of the crossbeam, both hooks are arranged facing the connecting wire arrangement area, and the hooks are provided with strip-shaped mounting grooves for mounting the battery core connecting wires.

[0008] With the above structure, the two hooks and the strip mounting grooves on the hooks can effectively fix the connecting wires, preventing them from shaking in the connecting wire arrangement area and affecting their service life. In addition, the hooks are installed in the form of rivets, which has the advantages of quick positioning and convenient installation.

[0009] Preferably, the upper end of the hook is provided with a mounting portion extending horizontally, the mounting portion being fixedly placed on the top of the crossbeam, and the mounting portion having a mounting hole for inserting a rivet. With this structure, the hook can be easily supported on the crossbeam via the mounting portion.

[0010] Preferably, the hook has a vertically downward extending portion at one end near the connecting wire arrangement area, a horizontally extending support portion at the lower end of the extension, and a vertically upward extending limiting portion at the end of the support portion away from the extension. The extension, support portion, and limiting portion together form the strip-shaped installation area. With this structure, the strip-shaped installation area prevents the connecting wire from wobbling after being installed on the hook, thus ensuring the overall service life of the connecting wire.

[0011] Preferably, the crossbeam is a rectangular structure with a clearance hole extending through its thickness at the top and a rivet hole extending downward into the clearance hole at the top of the crossbeam. The mounting part is a plate-like structure supported on the top of the crossbeam, and the mounting part is fixedly assembled to the top of the crossbeam by rivets passing through the mounting hole and the rivet hole. This structure avoids heat deformation of the crossbeam and ensures that the battery cell mounting area maintains good dimensional accuracy after the mounting hook is installed, thereby improving the installation accuracy of the battery pack.

[0012] Preferably, the support part is a vertically extending downward plate-like structure, and the mounting part is a horizontally extending plate-like structure, with the support part and the mounting part respectively attached to the two perpendicular sides of the rectangular structure. This structure increases the contact area between the hook and the crossbeam, ensuring the hook is stably installed on the crossbeam, and thus preventing the connecting cable from easily wobbling after being inserted into the strip mounting slot.

[0013] Preferably, both the clearance holes and the rivet holes are machined onto the crossbeam. This structure simplifies the manufacturing process of the crossbeam.

[0014] Preferably, the length of the limiting portion is shorter than the length of the extension portion. This structure avoids the limiting portion being too high and affecting the normal installation of the battery box as a whole.

[0015] Preferably, a wiring harness mounting hole is provided on the side beam near the crossbeam, and the connecting wire is disposed within the wiring harness mounting hole. This structure facilitates the connection of the connecting wire to the vehicle's electrical equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The battery box wiring harness bracket installation structure provided by this utility model can effectively fix the connecting wires by using the two hooks and the strip mounting groove of the hooks, so as to avoid the connecting wires shaking in the connecting wire arrangement area and affecting their service life.

[0018] 2. The hooks are fixed to the crossbeam by riveting, which eliminates the need for welding and prevents the crossbeam from deforming due to heat. This ensures that the battery cell installation area still has good dimensional accuracy after the hooks are installed, thereby improving the installation accuracy of the battery pack. Riveting installation is also a preferred option due to its fast positioning and simple installation. Attached Figure Description

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

[0024] like Figures 1 to 3 As shown, a battery box wiring harness bracket mounting structure includes a base plate 1 and side beams 2 surrounding the base plate 1. A crossbeam 3 is also installed on the base plate 1, which divides the base plate 1 into a battery core mounting area a and a connecting wire arrangement area b. At least two hooks 4 are riveted to the top of the crossbeam 3, and both hooks 4 are arranged facing the connecting wire arrangement area b. The hooks 4 have strip-shaped mounting grooves c, which are used to hold the battery core connecting wires.

[0025] With this design, the two hooks 4 and the strip mounting grooves c of the hooks 4 can effectively fix the connecting wires and prevent them from shaking in the connecting wire arrangement area b, which would affect their service life. In addition, the hooks 4 are installed in the form of rivets, which has the advantages of quick positioning and convenient installation.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the upper end of the hook 4 is provided with a mounting part 4a extending in the horizontal direction. The mounting part 4a is fixedly placed on the top of the crossbeam 3. The mounting part 4a is provided with a mounting hole 4a1 for inserting a rivet 5.

[0027] like Figure 4 As shown, the crossbeam 3 is a rectangular structure with a clearance hole 3b extending through its thickness at the top. The top of the crossbeam 3 has a rivet hole 3a extending downward into the clearance hole 3b. The mounting part 4a is a plate-like structure supported on the top of the crossbeam 3. The mounting part 4a is fixedly assembled to the top of the crossbeam 3 by rivets 5 passing through the mounting hole 4a1 and the rivet hole 3a. This fixing method eliminates the need for welding, avoids heat deformation of the crossbeam 3, and ensures that the battery core mounting area a still has good dimensional accuracy after the mounting hook 4 is installed, thereby improving the installation accuracy of the battery pack.

[0028] In this embodiment, both the clearance hole 3b and the rivet hole 3a are machined on the crossbeam 3. This design simplifies the manufacturing difficulty of the crossbeam 3.

[0029] Furthermore, the hook 4 has a vertically downward extending extension 4b at one end near the connecting line arrangement area b. A support 4c extends horizontally at the lower end of the extension 4b. A limiting part 4d extends vertically upward at the end of the support 4c away from the extension 4b. The extension 4b, support 4c, and limiting part 4d together form a strip-shaped mounting groove c, and the battery core connecting line is clamped in the strip-shaped mounting groove c.

[0030] In this embodiment, the length of the limiting part 4d is lower than the length of the extension part 4b. This design can prevent the limiting part 4d from exceeding the overall height of the battery box, thereby affecting the normal installation of the battery box.

[0031] Furthermore, the support part 4c is a vertically extending downward plate structure, and the mounting part 4a is a horizontally extending plate structure. The support part 4c and the mounting part 4a are respectively attached to the two perpendicular sides of the rectangular structure. This design increases the contact area between the hook 4 and the crossbeam 3, ensuring that the hook 4 is stably installed on the crossbeam 3, and thus ensuring that the battery core connecting wire will not easily shake after being clamped in the strip mounting slot c.

[0032] like Figure 1 As shown, a wiring harness mounting hole 2a is provided on the side beam 2 near the crossbeam 3, and the connecting wire passes through the wiring harness mounting hole 2a. This design facilitates the connection of the connecting wire to various electrical devices in the vehicle.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
